Canadian Forces Base Uplands (also CFB Uplands) was a Canadian Forces Base located in Ottawa, Ontario. Most of the land which formed the base was transferred to the Ottawa Macdonald-Cartier International Airport after the base was closed in the 1990s. Several military units continue to exist at the former base and the Canadian Forces continues to maintain military housing at the site. The former base is now known formally as "Canadian Forces Support Unit (Ottawa) - Uplands Site."
